Once again! another great shot and yet another small boat ruining it from far away. The two sale boats are just greatly positioned in the view, and the sunet makes it perfetto. Maybe you could remove that small one behind them with Photoshop! Anyways, it's a great shot, congrats.
Very nice sunset, great colors. Horizon shift can be fixed easily in an image editor. And blown-out highlights in the sun area are worth a try if you shot RAW with your Powershot. I would try another RAW conversion and make an "underexposed" TIF, then make a composite of this photo and the TIF converted for the sun (sounds complicated, but is not)
